Mason Tvert and the Marijuana Policy Project bought half a dozen billboards in New Jersey near MetLife Stadium to highlight the NFL's stance on marijuana. He also hand-delivered a petition to the league signed by thousands of people to overturn the drug's ban.
"Every team in the NFL has doctors prescribing prescription drugs to these players that are far more dangerous, far more addictive," Tvert said.
The legality of the issue has been a tough subject for the league. Commissioner Roger Goodell told the USA Today last week that the league could be open to allowing marijuana as a treatment option for head injuries or concussions.
"I'm not a medical expert. We will obviously follow signs," Goodell told the USA Today. "We will follow medicine and if they determine this could be a proper usage in any context, we will consider that. Our medical experts are not saying that right now."
The fact the league is even marginally open to a federally-scheduled drug is major movement.
Seahawks coach Pete Carroll indicated he is open to the idea of medical uses.
"We have to continue to explore and compete to find ways that are going to make our game a better game and take care of our players in the best way possible," he said on Monday.
Former kicker and current broadcaster David Treadwell lives in Colorado, another state that allows recreational marijuana. He is concerned about abuse if the league loosens up rules. He is not fully sold on the idea of the drug being used to help concussions and other injuries.
"Right now there just isn't enough information out there to really know what the medicinal effects could be," he said.
Tvert says the billboards are money well spent to keep the movement going and to change views of fans and the league on its biggest weekend.
"It's far less harmful than alcohol, it's less toxic. It's less addictive," he said.
